How do I owe money? I did get a raise half way through the year but it only effected my annual salary by maybe 8000

While everyone's situation is unique, but here are some common scenarios that may result in unexpected income tax debt: 

• You have multiple sources of income, which can place you in an inaccurate tax bracket.
• You changed jobs halfway through the year, bumping you into a new tax bracket.
